need windows xp coa

[the wharf rat]

I'm refurbishing an order of desktops for a nonprofit and I'm
short a windows coa (one of the systems doesn't have one so I won't load
windows on it). If you have a junk PC with a sticker laying around,
or an empty case with the coa that you haven't moved the windows to another
machine from or something similar I'll buy it from you for a couple
of bucks and some good karma or you could just lay it on me :-) Or I
could trade some other set of obsolete computer parts, most of which actually
even work.

Thanks in advance :-)
